Assessment of Childbirth-Related PTSD: Psychometric Properties of the German Version of the City Birth Trauma Scale

Background: About 3–4% of women in community samples suffer from childbirth-related posttraumatic stress disorder (PTSD). Surprisingly, the recently developed City Birth Trauma Scale (City BiTS) was the first diagnostic tool for childbirth-related PTSD covering DSM-5 criteria for PTSD. Since no questionnaire on childbirth-related PTSD is available in German, we aimed to validate a German translation of the City BiTS and to provide information on its psychometric properties.Methods: A community sample of 1,072 mothers completed an online survey, which included questions on sociodemographic and obstetric characteristics, the German version of the City BiTS, the Impact of Event Scale-Revised (IES-R), the PTSD Checklist for DSM-5 (PCL-5), Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-Anxiety).Results: Exploratory factor analysis (EFA) on a random split-half sample confirmed the previously reported two-factorial structure of the City BiTS. The factors “Childbirth-related symptoms” and “General symptoms” explained about 53%, 52% of variance. Internal consistency was good to excellent for the subscales and the total scale (Cronbach's Alpha = 0.89−0.92). In a confirmatory factor analysis (CFA) in the holdout sample the two-factorial solution reached the best model fit out of three models. Correlation analyses showed convergent validity of the City BiTS (total scale and subscales) with the IES-R and PCL-5 and divergent validity with the EPDS and the DASS-Anxiety.Limitations: Data were acquired in a community sample and prevalence rates might not be representative for mothers of high-risk groups, e.g., after preterm birth.Conclusions: The German version of the City BiTS is the first German questionnaire which allows to assess symptoms of childbirth-related PTSD according to DSM-5 criteria. Besides an improvement in clinical routine it will help to make data on prevalence of childbirth-related PTSD internationally comparable. In addition, this work provides a basis to assess childbirth-related PTSD in studies conducted with a longitudinal study design or in high-risk samples.

The Impact

Background. The Impact of Event Scale-Revised (IES-R) is often used as a self-report instrument for symptoms of post-traumatic stress (PTS). The objective of this study was to explore the reliability and validity of the Lithuanian IES-R in a sample of employees with exposure to workplace bullying in different occupations. Materials and methods. The original IES-R was translated into Lithuanian, and the comparability of content was verified through back-translation procedures. 294 employees with exposure to workplace bullying (52 teachers from the secondary schools of Kaunas, 56 family physicians, 101 nurses of internal medicine departments, 40 waiters, and 45 seafarers) were administered the Lithuanian IES-R and the General Health Questionnaire – 12 (GHQ-12) in order to verify some aspects of convergent validity. The exploratory factor analysis was used to verify the construct validity of the IES-R. Results. The reliability of the Lithuanian version of the IES-R was verified. Cronbach’s α of the total scale was 0.95. Exploratory factor analysis showed a clear factor structure with three independent dimensions: intrusion, avoidance and hyperarousal. Cronbach’s α for subscales of intrusion, avoidance and hyperarousal were 0.89, 0.85, and 0.88, respectively. The convergent validity was supported by positive correlations between the subscales (intrusion, avoidance, hyperarousal) and the GHQ-12. Conclusions. The results suggest that the self-reported Lithuanian IES-R is a valid instrument for assessing the dimensions of post-traumatic stress, has good psychometric properties, and may be applied in prolonged trauma-exposed populations.

The Impact

Abstract Background The Family Reported Outcome Measure (FROM-16) assesses the impact of a patient’s chronic illness on the quality of life (QoL) of the patient’s partner or family members. The aim of the study was to translate, explore the structure of and validate the FROM-16. Methods The questionnaire was translated from English into German (forward, backward, four independent translators). Six interviews with family members were conducted to confirm the questionnaire for linguistic, conceptual, semantic and experiential equivalence and its practicability. The final German translation was tested for internal consistency, reproducibility and test validity. Criterion validity was tested by correlating the scores of the FROM-16 and the Global Health Scale (GHS). Principal component analysis, factor analysis, and confirmatory factor analysis was used to assess the questionnaire’s structure and its domains. Reliability and reproducibility were tested computing the intraclass correlation coefficient (ICC) using one sample t-test for testing the hypothesis that the difference between the scores was not different from zero. Results Overall, 83 family members (61% female, median age: 61 years) completed the questionnaire at two different times (mean interval: 22 days). Internal consistency was good for the FROM-16 scores (Cronbach’s α for total score = 0.86). In those with stable GHS, the ICC for the total score was 0.87 and the difference was not different from zero (p = 0.262) indicating reproducible results. A bi-factor model with a general factor including all items, and two sub-factors comprising the items from the original 2-factor construct had the best fit. Conclusions The German FROM-16 has good reliability, test validity and practicability. It can be considered as an appropriate and generic tool to measure QoL of a patient’s partner or family member. Due to the presence of several cross-loadings we do not recommend the reporting of the scores of the two domains proposed for the original version of FROM-16 when using the German version. Thus, in reporting the results emphasis should be put on the total score. Trial registration: Retrospectively registered: DRKS00021070.

Abstract Background: The Personality Inventory for DSM-5 Brief Form (PID-5-BF) is a 25-item measuring tool evaluating maladaptive personality traits for the diagnosis of personality disorders(PDs). As a promising scale, its impressive psychometric properties have been verified in some countries, however, there have no studies about the utility of PID-5-BF in Chinese settings. The current study aimed to explore the maladaptive personality factor model which was culturally adapted in China and examine psychometric properties of the Personality Inventory for DSM-5 Brief Form among Chinese undergraduate students and clinical patients.Methods: 7155 undergraduate students and 451 clinical patients completed the Chinese version of PID-5-BF. 228 students were chosen randomly for test-retest reliability at a 4-week interval. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to discover the most suitable construct in Chinese, measurement invariance(MI), internal consistency, and external validity were also calculated.Results: An exploratory six-factor model was supported more suitable in both samples(Undergraduate sample: CFI = 0.905, TLI = 0.888, RMSEA = 0.044, SRMR = 0.039; Clinical sample: CFI = 0.904, TLI = 0.886, RMSEA = 0.047, SRMR = 0.060), adding a new factor“Interpersonal Relationships”. Measurement invariance across non-clinical and clinical sample was established (configural, weak, strong MI, and partial strict MI). Aside from acceptable internal consistency (Undergraduate sample: alpha=0.84, MIC=0.21; Clinical sample: alpha=0.86, MIC=0.19) and test-retest reliability(0.73), the association with 220-item PID-5 was significant(r = 0.93, p < 0.01), and six PDs measured by Personality diagnostic questionnaire-4+ (PDQ-4+) were correlated with expected domains of PID-5-BF.Conclusions: The PID-5-BF is a convenient and useful screening tool for personality disorders with a novel six-factor model in Chinese settings, with the main difference for the Negative Affect domain.

Mean Differences

The Personality Inventory for DSM-5 (PID-5) evaluates 25 maladaptive personality traits proposed in the Alternative Model of Personality Disorders. The questionnaire has been extensively investigated and validated in several languages. The current research sought to examine the psychometric properties of the instrument in a sample of nonclinical Romanian participants (N = 1276). Results indicated excellent internal consistency for the domain level, and very good reliability for the facet level. The assumption of unidimensionality was supported at both the domain and facet levels, apart from Risk Taking. Two domain scoring methods were also compared. One of them takes into consideration all the 25 lower order facets, whereas the other uses only 15 facets. Results show that mean differences across the two scoring methods were small, except for Disinhibition. Moreover, confirmatory factor analyses revealed slightly better fit indices for the model which uses 15 facets only. Lastly, the hierarchical structure of maladaptive personality traits was explored. Results are discussed in the light of previous literature.

The Impact

Background and Purpose: The purpose of this study was to determine a factor structure for the Impact of Miscarriage Scale (IMS). The 24 items comprising the IMS were originally derived from a phenomenological study of miscarriage in women. Initial psychometric properties were established based on a sample of 188 women (Swanson, 1999a). Method: Data from 341 couples were subjected to confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). Results: CFA did not confirm the original structure. EFA explained 57% of the variance through an 18-item, 4-factor structure: isolation and guilt, loss of baby, devastating event, and adjustment. Except for the Adjustment subscale, Cronbach’s alpha coefficients were ≥.78. Conclusion: Although a 3-factor solution is most defensible, with further refinement and additional items, the 4th factor (adjustment) may warrant retention.
